Knight Optical’s complete range of cost effective bandpass dichroic filters offer superior transmission, reflection and absorption characteristics

Dichroic bandpass filters are designed to transmit highly over a specific limited bandwidth while reflecting all other wavelengths. Their design allowed them to isolate the desired wavelength. Dichroic filters offer superior contrast between transmitted and reflected wavelengths. Having negligible absorption they are suitable for high powers and do not show the strong fluorescence of certain glass filters.

Our dichroic bandpass filters are available in a range of wavelengths and are supplied in standard 12.5mm and 25mm diameter or 50mm square types. We are happy to cut and edge filters for non standard sizes to suit your application.
